Is there anyway to have a link that will force the browser to download regardless of how the mime is setup in their browser?  I want to let people download mp3 files without have to right-click and save as.

save the below code as down.aspx.

call this file and pass one parameter specifying the name of file.

e.x.

response.redirect("down.aspx?file=" & filenamefromVariable)

This will force the file under the "upload directory" to be downloaded

<%@ Page language="vb" runat="server" explicit="true" strict="true" %>
<script language="vb" runat="server">
Sub Page_Load(Sender As Object, E As EventArgs)
	Dim filenames As String = Request.QueryString("file")
	'-- if something was passed to the file querystring
	If filenames <> "" Then
		Dim strRequest As String = "./upload/" & Request.QueryString("file")
		Dim fileNameasSave As String = Request.QueryString("name")
		'get absolute path of the file
		Try
			Dim path As String = Server.MapPath(strRequest)
			'get file object as FileInfo
			Dim file As System.IO.FileInfo = New System.IO.FileInfo(path)
			'-- if the file exists on the server
			If file.Exists Then
				'set appropriate headers
				Response.Clear()
				Response.AddHeader("Content-Disposition", "attachment; filename=" & fileNameasSave)
				Response.AddHeader("Content-Length", file.Length.ToString())
				Response.ContentType = "application/octet-stream"
				Response.WriteFile(file.FullName)
				Response.End
			'if file does not exist
			Else
				Response.Write("This file does not exist.")
			End If
			'nothing in the URL as HTTP GET
		Catch ex As Exception
			Response.Write(ex.Message)
		End Try
	Else
		Response.Write("Please provide a file to download.")
	End If
End Sub
</script>

My apologies, I was not clear enough.  I want to force the download (or prompt to save file) using a file on a different server?  Is this possible?  If not I guess I could put the down.aspx on that server.

i think, without using any server-side code its nearly impossible as the content is originated from the server, and if you don't have access to server resources then how can u control the data (response) coming from that server ??

Logically u should have some access to the server.
